f2fs: make exit_f2fs_fs more clear

2016-05-18T20:57:31+00:00

init_f2fs_fs does: 1) f2fs_build_trace_ios 2) init_inodecache 3) create_node_manager_caches 4) create_segment_manager_caches 5) create_checkpoint_caches 6) create_extent_cache 7) kset_create_and_add 8) kobject_init_and_add 9) register_shrinker 10) register_filesystem 11) f2fs_create_root_stats 12) proc_mkdir exit_f2fs_fs should do cleanup in the reverse order to make the code more clear.

This can reduce page counting overhead. Signed-off-by: Jaegeuk Kim

f2fs: add fault injection to sysfs

2016-05-16T22:32:02+00:00

This patch introduces a new struct f2fs_fault_info and a global f2fs_fault to save fault injection status. Fault injection entries are created in /sys/fs/f2fs/fault_injection/ during initializing f2fs module. Signed-off-by: Sheng Yong Signed-off-by: Jaegeuk Kim

fscrypto/f2fs: allow fs-specific key prefix for fs encryption

2016-05-07T17:32:33+00:00

This patch allows fscrypto to handle a second key prefix given by filesystem. The main reason is to provide backward compatibility, since previously f2fs used "f2fs:" as a crypto prefix instead of "fscrypt:". Later, ext4 should also provide key_prefix() to give "ext4:". One concern decribed by Ted would be kinda double check overhead of prefixes. In x86, for example, validate_user_key consumes 8 ms after boot-up, which turns out derive_key_aes() consumed most of the time to load specific crypto module. After such the cold miss, it shows almost zero latencies, which treats as a negligible overhead. Note that request_key() detects wrong prefix in prior to derive_key_aes() even.
